How Much Does Furnace Repair Cost in Phoenix? [2025 Data]

Furnace repair costs in Phoenix average $346, and most projects total between $121 and $589. The price you’ll pay will depend mostly on the specific repair you need and the type of furnace you have. Labor costs in Phoenix are above average due to a high cost of living, but since most furnaces in the area are electric, repairs are often simple and affordable, leading to below-average totals.

Furnace Repair Cost Factors

Furnace repairs in Phoenix, AZ, can cost as little as $50 if you just need something as simple as a filter replacement, but prices can climb as high as $1,800 if a major component needs repair or replacement.

Repair Cost by Part

Regardless of their fuel source, furnaces are complex appliances that have a lot of moving parts. Some of those parts significantly influence furnace repair costs, while others are simpler and less costly to repair.

Here is the average furnace repair cost based on the part:

Most furnaces in Phoenix use electricity as a fuel source since the heating demands in the hot climate are so minimal, so some of these components and costs are only for oil or gas furnaces and aren’t applicable for most homeowners. These include burners, combustion chambers, flame sensors, flue pipes, gas valves, and ignitors.

Maintenance Cost

A furnace requires regular maintenance in order to operate efficiently. Otherwise, dust and other debris can clog burners, the pilot light, and other parts, causing more wear and tear on the system. 

A furnace inspection costs $80 to $100 on average, and you need to schedule an inspection at least once per year to keep your system running smoothly. An advanced inspection, which includes cleaning and a tuneup, costs $125 to $200. 

Additional maintenance costs include filters and air duct cleanings. You need to replace the filters once every 90 days, which will cost $4 to $140 per year. Schedule duct cleanings every three to five years, and expect to spend $275 to $500 for the cost of cleaning air ducts.

Routine maintenance is wise in colder climates, where constant furnace use can wear down moving parts and lead to inefficiencies. However, it’s also important in areas with hotter climates, like Phoenix, since maintenance can help keep heating equipment that you use infrequently in good health. Electric furnaces that sit unused for long periods can suffer from corrosion and dust buildup, which can contribute to larger problems over time.

Cost per Hour

Furnace repairs cost $50 to $150 per hour for the labor, plus you’ll need to budget for the cost of parts. Small repairs may be billed at a $100 to $200 minimum rather than by the hour. 

One of the quickest repairs is to replace a dirty filter, which only takes a few minutes and is easy to DIY. Some of the more difficult, time-consuming parts to repair include the blower motor, the draft inducer motor, coils, and the heat exchanger.

HVAC Pro Costs

Hiring an HVAC pro in Phoenix will cost you between $130 and $310 for labor alone, meaning labor can account for anywhere between 40% and 90% of your total. For major furnace repairs, you could pay as much as $1,000 for labor. The cost of living in Phoenix is close to 10% higher than the national average, which means labor on a per-hour basis will cost more than it would in most other cities.

More involved furnace repairs in Phoenix will require a permit. Ask your HVAC pro if your project needs one. If it does, the city will charge a flat fee of $75, so be sure to budget separately for that fee.

Do Furnace Repairs Increase Home Value?

Furnace repairs won’t increase your home value since most buyers expect mechanicals to be in good working order. In some areas, furnace repair can help prevent your property value from dipping, but in Phoenix, where home heating isn’t always a primary concern given the hot climate, furnace repair is unlikely to make much of a difference one way or the other.

Air conditioning is far more important in Phoenix and is necessary in the extremely hot summers. If your AC and your furnace are approaching the end of their useful lifespans, you could maximize your return on investment (ROI) by installing a heat pump or ductless mini-splits that can provide both heating and cooling.
